   4  * changed these to function pointers.. it saves cycles and will allow
   5  * the irq dependencies to be split into different files at a later date
   6  * sun4c_irq.c, sun4m_irq.c etc so we could reduce the kernel size.
   7  * Jakub Jelinek (jj@sunsite.mff.cuni.cz)
   8  * Changed these to btfixup entities... It saves cycles :)
